PEAT-DRYING APPARATUS.

Specification of Letters Patent.

Patented Sept. 1 9, 1905.

Application filed June 2, 1904. Renewed April 21, 1905- Serial No. 256,801.

- Farnham, county of Missisquoi, and JOSEPH ALPHONSE RAoUL BEDARD, of Quebec, county of Quebec, in the Province of Quebec, Canada, subjects of the King of Great Britain, have invented certain new and useful Improvements in Peat-Drying Apparatus; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to new and useful improvements in drying apparatus designed especially for use in drying peat incidental to the process of preparing such peat for use as fuel, and comprises certain features of novelty in the construction and operation thereof and in the appurtenant connections therefor by means of which impurities and foreign matter are expelled from the peat, all as hereinafter more fully described,-and specifically pointed out in the claims.

The object of 'theinvention is to provide an apparatus of the character indicated by means of which peat maybe freed from foreign substances-such as sticks, stones, &c.when taken from the bog and passed through the apparatus herewith illustrated, so that the peat is partially dried therein and rendered suitable for compression into briquets Without the admixture of any foreign substances for the purpose of binding the particles thereof together.

The apparatus and its appurtenant parts are illustrated in the annexed drawings to some extent diagrammatically for convenience of illustration, owing to the fact that a number of elements which are well known in the art are used in connectionwith the general apparatus, and while we do not claim specifically such well-known elements except as a correlation of result may be produced from their operation in our apparatus we do not specifically disclaim any of the features herewith illustrated or the process herein partiallydisclosed, as such process will form the subjectmatter of a separate application or applications for patents.

Referring to the annexed drawings, wherein similar numerals of reference indicate corresponding parts in all the views, Figure 1 is a side elevational view of our improved apparatus, partly diagrammatically illustrated. Fig. 2 is an approximate end elevation, being taken on the line 2 2 of Fig. 1. Fig. 3 is a transverse vertical sectional view taken on the line 3 3 of Fig. 4- Fig. 4 is a longitudinal vertical sectional view of that part of the apparatus disclosed in Fig. 1 within the lines 4 4t and hereinafter specifically referred to as a breaker-chamber and breaker. Fig.

5 is a transverse sectional view taken on the tional view taken on the line 7 7 of Fig. 6,

with the addition of the steam-supply main and lateral feed-pipe being connected to the coils disclosed in Fig. 7. Fig. 8 is adetached detail sectional view taken vertically through the pug-mill on the line 8 8 of Fig. 9. Fig. 9 is a vertical sectional view taken on the line 9 9 of Fig. 8. Fig. 10 is an enlarged detail view of one of the conveyer-blades hereinafter referred to. Fig. 11 is a similar view of the opposite side of said blade, and Fig. 12 is a vertical sectional view taken on the line 12 12 of Fig. 1.

For convenience of description several of the machine elements are referred to by arbitrary names, and wherever used such names indicate said parts or mechanical equivalents thereof, whether constructed in the same manner or in any other manner, whereby such parts may be capable of performing the required function ascribed to the parts or elements so named. For example,the breaker includes means whereby rotatable elements or fingers are applied for the purpose of ejecting from the peat such foreign matter as sticks, stones, &c., which it is desired to eliminate from the finished product. The conveyer includes any required number of propellerblades or their mechanical equivalent adapted to cause the peat to travel in its course through the apparatus. The apertured wall or perforated walls include either a wall or walls formed of any number of elements,

with passages or apertures therethrough or.

between the same whereby the peat may-pass from one side to the other of such wall.- Pugmill includes any means adaptedto perform Ioo the usual function of such mills, whether of the form shown or any other suitable construction. Heater includes a fuel-combustion chamber and appurtenant connections or other known means for raising the temperature, and likewise superheater includes a chamber heated directly by the prod- -ucts of combustion or by any other means, such as steam, &c., for accomplishing the purpose, as will be evident from the annexed illustration of our invention, wherein the heater and the superheater are one and the same apparatus.

That the apparatus may be better understood reference will be made to the parts in substantially the order in which the elements referred to become operative for accomplishing the purpose of the machine, as follows:

1 is a conveyer or elevator which may be used for the purpose of elevating the moist peat to the machine or dumping it into the hopper 2, through which it is conducted into the breaker-chamber 3, wherein the shaft 4, provided with the adjusting extension 5, rotates. Upon the shaft 4: are any suitable number of propeller-bladesfi, adapted to drive the peatlongitudinally of the chamber 3, while breaker-arms 7 are carried by the shaft 4:, but which are not caused to rotate therewith. Interposed between the propellers 6 and breakerarms 7 are fingers 8, which are keyed to the shaft and rotate with it, or said fingers are provided with non-circular seats adapted to rest upon and be engaged by non-circular portions of said shaft, as shown in Fig. 3, whereby as the peat is forced through the breaker-chamber 3 the arms 7 and 8 cooperate to drive sticks and large particles of earth or stones and other matter from the mass of wet peat into the breaker-depositing chamber 9, which extends laterally from the chamber 3, as best shown in Fig. 3 of the drawings.

As will be noted in Fig. 3, the arms 7 are mounted upon the shaft 4, which is non-circular in cross-section. Between the shaft and these arms is a friction-disk 7 which rotates with the shaft and by frictional engagement carries the arms 7 in the direction indicated by the arrow in that figure. The free ends of the arms 7 extend into the chamber 9, as shown, and when actuated contact with the shoulder 9 with sufficient force so that they are thereby returned to the position shown in Fig. 3, from which position they are again elevated during continued rotation of said shaft, thus causing said arms 7 to travel only for that portion of a circle between the lower and upper walls of chamber 9.

The chamber 9 is provided with a door 10, having a suitable locking means 11 of any convenient description for the purpose of se- 'curing such door in closed position, and it will be evident that at intervals such door 10 should be opened and the contents of the chamber 9 removed therefrom to prevent an excessive accumulation therein.

Any suitable number of breaker arms and fingers 7 and 8 may be provided within the breaker-chamber according to the capacity of the machine, and the relative proportion thereof may be changed at will, according to the class of material to be operated on and the known foreign matter contained therein.

The breaker-chamber 3 opens into a drying-chamber or conveying-chamber 12, which is shown in elevation in Fig. 1. Extending longitudinally of the drying-chamber 12 is a main steam -supply pipe 13, from which branches 14 extend and communicate with the upper convolution of the coils 15, which comprise what are herein referred to as apertured walls, such apertures consisting of the spaces or openings between the several convolutions of such pipe 15. Supporting the apertured walls in position are angle-irons 16, which, as shown in Fig. 6, are disposed at each side of said walls, so as to better enable them to serve as strainers and resisting means for the peat to be projected therethrough. The lower portion of the chamber 12 is curved, as shown in Fig. 7, and the bottom formed by the curved plate 17 is apertured at convenient intervals for the insertion of a plurality of such aperturedwalls 15 between the bottom sections produced by such openings. Interposed between the apertured walls are conveyer-blades 18, shown in detail in Figs. 10 and 11 and comprising the hubs 19, having the integral arms 20, to which are bolted or otherwise secured the face-plates 21, while set-screws 22 are projected through the hubs 19 for the purpose of securing such conveyerblades upon the shaft 4:, which is an extension of the shaft 1 before referred to and in alinement therewith.

The conveyers 18 will cause the peat driven from the chamber 3 into the heating-chamber 12 to be passed through the perforated walls 15, whereby a separation of the particles of such peat will result, owing to the action of the conveyers, which serve as disintegrating as well as conveying means, and the relativelyfine mesh caused by the close promimity of the coils constituting the walls 15. A relatively large number of such walls 15 are provided within the chamber 12, and according to the capacity of the apparatus the number of such walls may be increased or diminished as experience will demonstrate to be most desirable.

1n convenient proximity to the heatingchamber 12 is provided a suitable heating apparatus, which for convenience of illustration is shown in the drawings as comprising the combustion-chamber 25, which may be of any suitable character, within and through which project a number of coils of pipe, as follows: Near the feed end of the apparatus is placed a blower 26, from which extends a pipe 27, which passes into and through the heater, thence rises, as shown in Fig. 1, and communicates with the feed end of the drying-chamber 12, whereby a hot blast is projected into such drying-chamber. At the opposite end of the apparatus a fan 28 is provided, from which extends the conduit 29 through the heater and to the discharge end of the drying-chamber, where such pipe 29 enters the heating-chamber. A steam-supply pipe 30, which leads, preferably, from the exhaust of the engine used to drive the apparatus, passes through the heater, wherebyv steam therein is superheated and conducted to the supply-main 13, which main is closed by suitable plugs 31 at its ends, as shown in Fig. 1 of the drawings, so that steam therein will be permitted to pass through the branches 14, thence through the coils 15, and exhaust through the branches 32 into the exhaustmain 33, which leads to atmosphere, as indicated by thearrow in Fig. 1.

Leading from the upper portion of the combustion-chamber 25 is a conduit 34, which leads to approximately the middle portion of the heating-chamber 12, whereby the spent products of combustion and heated gases from the combustion-chamber are carried into said heatingchamber, thereby utilizing to the fullest extent possible all of the available heating means for the purpose of drying the peat without carbonizing the same. Connecting with the combustion-chamber intermediate its ends, and preferably between the hot-air conduits 27, 29, and 34, are exhaust-conduits 35, which lead to exhaust-fans 36, whereby the aqueous vapors generated within the heating-chamber l2are exhausted to atmosphere, and the dry air and gases and the superheated steam in the apertured walls are rendered available to their fullest capacity for the purpose of evaporating moisture from the peat passed through the said heating-chamber. The shaft 4 4 is rotated by means of the beveled gear 37, meshing with the corresponding beveled gear 38 upon the shaft 39, upon which is placed a pulley 40, driven from the driving-shaft 41, and the said blast-fans and exhaust-fans are likewise driven by suitable belting or other well-known connections from the engine represented diagrammatically in 42. When the peat has been passed the entire length of the heating-chamber 12 by means of the conveyers, such peat passes from the said chamber into a suitable pug-mill 44, in which further disintegration of such peat takes place, after which it is fed by the feedwheel thereof into the conduit 45.. In convenient proximity to the pug-mill 44 is a blastfan 46, discharging into said conduit 45, by means of which the peat. which is now comparatively dry, is fed through the heatingchamber 25 by means of such blast generated by the fan 46, and after passing through the heater the peat is discharged from the pipe 45 to any suitable place of deposit, or, if desired, is carried to any suitable briqueting machine (not shown) for the purpose of forming it into briquets for the market.

As will be evident from the foregoing description, the invention comprises aself-contained apparatus wherein each of the elements contributes its quota to the general re, sult ofcleaning, disintegrating, and drying the peat in its passage through the apparatus, and by means of the apparatus hereinbefore particularly described we are enabled to take peat which is in a moist condition and conduct it through the machine, and thereby produce an article of commerce wherein all of the caloric valueof the peat is retained, yet placing such peat in the best possible condition for formingit into the usual briquets for consumption.

While we have shown in the accompanying drawings the preferred form of our invention, it will be understood that we do not limit ourselves to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of our-invention, and we therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.

43 is a roller-brush cooperating with the serrations 43", which serves to disintegrate the peat from the heating-chamber to the pugmill 44.
